The Meritorious Unit Commendation is a mid-level unit award of the United States military which is awarded to any military command which displays exceptionally meritorious conduct in the performance of outstanding service, heroic deeds, or valorous actions.

Each military service issues its own version of the Meritorious Unit Commendation. The United States Army version is typically referred to as the "Meritorious Unit Commendation" while the other military branches use the service name as a prefix (for example Navy Meritorious Unit Commendation). The Meritorious Unit Commendation is abbreviated (and often pronounced) as "MUC."
